In clk_set_default_get_by_id ret is passed to ERR_PTR but nothing is
done with the value that this calculates which is obviously not the
intention of the code. This is confirmed by the code around where this
function is called.
Instead return the value from ERR_PTR.

The cv1800b_clk_setfield function returns void, but was doing "return
writel(...);" and while seemingly having a void function return a void
function is not a warning, when readl is a macro this problem is shown.
Correct the code to instead simply call writel.

Misc update on firmware scmi:
- Typo fix
- Use io helpers
- Use PAGE_SIZE for arm64
- Add IN_USE error code
- Add more error info
- Support scmi max rx timeout in mailbox
- Add myself as scmi maintainer, AKASHI contributed most code, but
seems he is not invovled in the developement anymore, I volunteer to
help here.
Some items on list that I am thinking to add:
- align with linux kernel to use cpu_to_le32 and le32_to_cpu, but have not find
a good way to use the helpers.
- Add SCMI version negotiation as Linux Kernel

Use dev_dbg to dump device name, dev_dbg also a encapsulation call

SoCFPGA updates for v2025.10:
CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/27762
This pull request brings a set of updates across SoCFPGA platforms
covering Agilex5, Agilex7, N5X, and Stratix10. The changes include:
* Agilex5 enhancements:
- USB3.1 enablement and DWC3 host driver support
- System Manager register configuration for USB3
- Watchdog timeout increase and SDMMC clock API integration
- dcache handling improvements in SMC mailbox path
- Enable SPL_SYS_DCACHE_OFF in defconfig
* Clock driver improvements:
- Introduce dt-bindings header for Agilex clocks
- Add enable/disable API and EMAC clock selection fixes
- Replace manual shifts with FIELD_GET usage
* DDR updates:
- IOSSM mailbox compatibility check
- Correct DDR calibration status handling
* Device tree changes:
- Agilex5: disable cache allocation for reads
- Stratix10: add NAND IP node
- Enable driver model watchdog
- Enable USB3.1 node for Agilex5
* Config cleanups:
- Simplify Agilex7 VAB defconfig
- Remove obsolete SYS_BOOTM_LEN from N5X VAB config
- Enable CRC32 support for SoCFPGA
- Increase USB hub debounce timeout
Overall this set improves reliability of DDR and cache flows,
adds missing USB and MMC features for Agilex5, and refines clock
and configuration handling across platforms.
This patch set has been tested on Agilex 5 devkit, and Agilex devkit.
FIELD_GET() macro is used during EMAC clock source selection
for better code readability and maintainability.

In exynos7420_peric1_get_rate the variable ret is declared as an
'unsigned int' but is then used to receive the return value of
clk_get_by_index which returns an int. The value of ret is then tested
for being less than 0 which will always fail for an unsigned variable.
Fix this by declaring ret as an 'int' so that the test for the error
condition is valid.

The use of the unsigned variable 'i' as a loop index leads to the test
for i being non-negative always being true. Instead declare 'i' as an
int so that the for loop will terminate as expected.
If the original for loop completes 'i' will be 1 past the end of the
array so decrement it in the subsequent error path to prevent an out of
bounds access occurring.
